Nisi Prius Trial Courts: The Nonbinding Nature of the Same Motions Before Different Judges During the Course of a Case
Published .
A motion is filed in a Maryland circuit court.
Judge A denies it.
Months later, after the case has been reassigned, Judge B confronts essentially the same legal issue.
Is Judge B bound by Judge A’s ruling?
Frequently, no.
This can surprise lawyers—and occasionally judges—because it sounds inconsistent with familiar concepts such as stare decisis, law of the case, res judicata, collateral estoppel, and the general expectation that courts should not repeatedly reconsider matters already decided.
But Maryland has long recognized an important distinction between a final judgment and an interlocutory ruling of a trial court.
As a general rule, one Maryland trial judge is not bound by an earlier interlocutory ruling made by another judge of the same court in the same case.
The second judge ordinarily possesses discretion to reconsider the issue de novo.
That means a plaintiff can win a motion to dismiss before one judge, survive summary judgment before another, and still lose on a motion for judgment at trial before a third.
It also means a defendant whose motion was denied once is not necessarily prohibited from raising the issue again.
But the doctrine does not mean that lawyers are free to engage in endless judge-shopping by repeatedly filing an identical motion until somebody grants it.
Understanding the distinction requires understanding what an interlocutory ruling actually is.
What Does “Nisi Prius” Mean?
“Nisi prius” is an old common-law expression referring essentially to a trial court—the court where factual and legal issues are initially heard and decided before appellate review.
Maryland appellate opinions have continued to use the phrase when discussing the authority of one trial judge to reconsider an interlocutory ruling made by another.
The terminology may be old.
The doctrine is not.
It arises regularly in modern Maryland civil litigation.
The Basic Maryland Rule
Maryland’s appellate courts have stated the principle directly.
In State v. Frazier, 298 Md. 422, 449, 470 A.2d 1269 (1984), the Supreme Court of Maryland explained that, as a general principle, one trial judge ruling on a matter is not bound by a prior ruling in the same case by another judge of that court. The later judge, in the exercise of discretion, ordinarily may consider the matter de novo.
The principle has deep Maryland roots.
In Placido v. Citizens Bank & Trust Co., 38 Md. App. 33, 45, 379 A.2d 773 (1977), the appellate court quoted the earlier decision in National Liberty Insurance Co. of America v. Thrall, 181 Md. 19, 22–23, 27 A.2d 353 (1942):
There is no rule requiring one nisi prius judge to accept as final and conclusive another trial judge’s pretrial legal rulings.
That principle remains part of Maryland law.
Maryland Rule 2-602 Explains Much of the Reason
Maryland Rule 2-602(a) provides the procedural foundation for the rule in multi-claim or multi-party litigation.
An order that adjudicates fewer than all claims, or the rights and liabilities of fewer than all parties, ordinarily:
-
does not terminate the action;
-
does not constitute a final judgment; and
-
remains subject to revision before entry of a judgment adjudicating all claims and all parties’ rights and liabilities.
That last proposition is crucial.
An interlocutory ruling is not merely unappealable in the ordinary course.
It remains within the trial court’s revisory authority.
The Supreme Court of Maryland has emphasized that interlocutory summary-judgment rulings remain subject to circuit-court review where the governing rules and interests of justice permit reconsideration.
“Law of the Case” Does Not Mean What Lawyers Sometimes Think It Means
A lawyer may respond:
But Judge A already decided that. Isn’t it law of the case?
Not necessarily.
Maryland’s law-of-the-case doctrine principally concerns legal determinations made by an appellate court that bind the trial court and the parties in later proceedings in that same case, as well as other circumstances involving final determinations.
It generally does not convert every interlocutory trial-court ruling into immutable law simply because another judge previously decided the issue.
Maryland authority expressly recognizes that an interlocutory ruling by one trial judge ordinarily does not become binding law of the case for another trial judge.
That distinction is fundamental.
Stare Decisis Is Something Else
Stare decisis is also different.
A circuit court judge is bound by controlling precedent from Maryland’s appellate courts.
A circuit judge cannot simply decide:
I disagree with the Supreme Court of Maryland, so I will follow my own interpretation.
But Judge A’s interlocutory ruling in an individual circuit-court case is not appellate precedent.
Judge B is not bound by Judge A in the same way both judges are bound by a controlling decision of the Supreme Court of Maryland.
Thus:
Appellate precedent may bind Judge B.
Judge A’s interlocutory ruling ordinarily does not.
Res Judicata and Collateral Estoppel Are Different Too
Res judicata and collateral estoppel concern the preclusive consequences of judgments and determinations satisfying the requirements of those doctrines.
They are not general rules prohibiting a trial court from reconsidering every interlocutory ruling entered during an ongoing action.
The fact that an issue has been argued and decided once does not automatically make that decision a final judgment entitled to preclusive effect.
Before invoking preclusion terminology, ask:
Was there actually a final judgment or otherwise qualifying final determination?
If not, the analysis may instead involve the trial court’s authority to revise an interlocutory order.
You Won the Motion. You Did Not Necessarily Win the Issue.
This is the practical lesson.
Suppose the defendant files a motion to dismiss.
The defendant argues that the complaint fails to state a legally cognizable claim.
Judge A denies the motion.
The plaintiff may understandably believe:
That issue has been decided.
Not necessarily.
Discovery proceeds.
The defendant later moves for summary judgment.
The defendant again argues that the claim fails as a matter of law, now on a developed evidentiary record.
Judge B may consider the issue.
The earlier denial of the motion to dismiss does not necessarily bind Judge B.
Howard v. Montgomery Mutual: Motion to Dismiss Denied, Summary Judgment Later Considered
Maryland authority specifically addresses this progression.
In Howard v. Montgomery Mutual Insurance Co., 145 Md. App. 549, 554, 805 A.2d 1167 (2002), the Appellate Court concluded that denial of a motion to dismiss was an interlocutory order that did not constitute law of the case and did not preclude another judge from considering a later motion for summary judgment.
A recent Maryland appellate decision reiterated precisely that proposition: because denial of a motion to dismiss is not a final judgment, an earlier denial did not bind a later judge considering summary judgment.
That makes sense procedurally.
A motion to dismiss ordinarily tests the legal sufficiency of the pleading.
Summary judgment examines whether, on the developed record, a genuine dispute of material fact exists and whether a party is entitled to judgment as a matter of law.
The legal issue may overlap.
The procedural posture and factual record may be quite different.
Summary Judgment Can Be Denied Once and Granted Later
The same principle applies to successive summary-judgment motions.
Maryland Rule 2-501 permits a party to seek summary judgment when there is no genuine dispute of material fact and the party is entitled to judgment as a matter of law.
A denial of summary judgment ordinarily is interlocutory.
Maryland appellate decisions have long recognized that a trial court may later grant a renewed motion for summary judgment even though an earlier motion was denied.
In Yamaner v. Orkin, 313 Md. 508, 516, 545 A.2d 1345 (1988), the Supreme Court of Maryland recognized the trial court’s authority later to grant a renewed summary-judgment motion.
Likewise, Joy v. Anne Arundel County, 52 Md. App. 653, 660–61, 451 A.2d 1237 (1982), recognized that summary judgment may be granted later in a case even though it was denied earlier.
And Ralkey v. Minnesota Mining & Manufacturing Co., 63 Md. App. 515, 522, 492 A.2d 1358 (1985), explained that denial of summary judgment does not preclude resubmission later in the proceedings.
Changed Facts or Law Make Reconsideration Particularly Appropriate
Although the court possesses revisory authority over interlocutory orders, a renewed motion becomes particularly compelling where something material has changed.
Examples include:
-
important discovery has been completed;
-
a deposition undermines an essential factual allegation;
-
an expert has been excluded;
-
the plaintiff has abandoned a theory;
-
documents establish facts previously disputed;
-
a controlling appellate decision has been issued;
-
a statute or rule has changed;
-
the legal theory has been refined;
-
the first motion was decided on the pleadings and the second on evidence; or
-
the evidentiary record at trial differs from the pretrial record.
Yamaner specifically recognized the significance of a change in fact or law substantially justifying resubmission.
But Changed Circumstances Are Not Necessarily a Jurisdictional Prerequisite
The broader Maryland rule is not simply:
A second judge may reconsider only if something has changed.
The doctrine is broader.
Where the earlier ruling remains interlocutory, the court retains revisory authority, and a later judge ordinarily has discretion to consider the matter de novo unless a statute, rule, appellate mandate, final judgment, or other controlling principle prevents reconsideration.
Changed circumstances may make reconsideration more persuasive.
They are not the source of the court’s underlying power.
The Same Judge Can Reconsider Too
The doctrine is often discussed because cases move among different judges.
But the fundamental concept concerns the interlocutory character of the ruling, not the identity of the judge.
A judge may reconsider that judge’s own interlocutory ruling.
A successor judge may reconsider it as well.
The power belongs to the court.
That is why Rule 2-602 speaks in terms of the order remaining subject to revision rather than creating a personal ownership interest in the judge who first decided the motion.
Partial Summary Judgment Can Be Especially Deceptive
Suppose Judge A grants partial summary judgment on one issue but other claims remain unresolved.
Counsel may begin preparing for trial on the assumption that the issue decided by partial summary judgment has permanently disappeared.
That assumption can be dangerous if the order remains interlocutory under Rule 2-602.
The Supreme Court of Maryland has recognized the continuing revisory authority of a circuit court over interlocutory summary-judgment rulings.
This does not mean a trial judge should casually undo an earlier partial summary judgment on the eve of trial.
It means counsel must distinguish between an interlocutory adjudication and a truly final judgment.
Rule 2-602(b) Can Change the Analysis
Maryland Rule 2-602(b) permits a circuit court, in appropriate circumstances, to direct entry of a final judgment as to one or more but fewer than all claims or parties when the court expressly determines that there is no just reason for delay.
That is an exception to the ordinary rule against piecemeal final judgments.
Once a ruling becomes a properly certified final judgment, the analysis changes substantially.
Rule 2-602(b) certification is therefore not merely a mechanism for creating an immediate appeal.
It can alter the status of an order that otherwise would remain interlocutory and freely revisable.
Maryland appellate courts have cautioned, however, that certification should not become routine; the preference remains against piecemeal appeals.
A Motion to Dismiss, Summary Judgment, and Motion for Judgment Are Not the Same Motion
This distinction also explains why the apparent repetition may be more superficial than real.
Consider the progression:
Motion to Dismiss
The court generally assumes properly pleaded factual allegations and asks whether the complaint states a legally sufficient claim.
Summary Judgment
The court examines the evidentiary record and determines whether there is a genuine dispute of material fact and whether a party is entitled to judgment as a matter of law.
Motion for Judgment at Trial
The court evaluates the evidence actually produced at trial under the governing standard and asks whether there is legally sufficient evidence to permit the issue to go to the jury.
The underlying legal proposition may be identical.
The record is not.
Therefore:
Winning at one procedural stage does not guarantee winning at the next.
Surviving Summary Judgment Does Not Guarantee a Jury Decision
This is particularly important for plaintiffs.
A plaintiff survives summary judgment.
The judge concludes that the pretrial record contains enough evidence to create a triable dispute.
The plaintiff then presents the case at trial.
The defendant moves for judgment.
The plaintiff responds:
But another judge already ruled that this was for the jury.
That may not carry the day.
The question at trial is whether the evidence actually admitted is legally sufficient.
The trial judge is not necessarily bound by an earlier prediction based upon the summary-judgment record.
A case can therefore survive summary judgment and still end before reaching the jury.
The Reverse Can Occur Too
Suppose Judge A initially grants partial summary judgment.
Later developments demonstrate that the ruling rested upon an incomplete record or erroneous legal premise.
If the order remains interlocutory, the trial court may possess authority to revise it.
The fact that the ruling favored one side does not make it more final.
Interlocutory status cuts both ways.
A Different Judge Is Not an Appellate Court
There is nevertheless an important institutional distinction.
Judge B is not “reversing” Judge A in the appellate sense.
Both are judges of the same circuit court.
The second judge is exercising the circuit court’s continuing authority over an interlocutory matter.
This helps explain why terminology such as “appeal to another circuit judge” is misleading.
There has been no appeal.
There has been reconsideration within a case that remains pending in the same court.
Judicial Comity Still Matters
The fact that a second judge may reconsider does not mean the second judge necessarily should.
Judges understandably accord respect to decisions already made by colleagues.
Stability matters.
Efficiency matters.
Fairness matters.
Parties organize discovery, expert preparation, settlement positions, and trial strategy around judicial rulings.
Repeated reversal of interlocutory decisions without good reason can create unnecessary expense and uncertainty.
The Maryland rule therefore is best understood as a doctrine of discretionary revisory authority, not a command that every new judge reconsider everything previously decided.
“Not Binding” Does Not Mean “Meaningless”
An earlier ruling can remain highly persuasive.
Judge B may conclude:
Judge A considered this carefully, the record has not materially changed, the law has not changed, and I see no reason to revisit it.
That is entirely consistent with the doctrine.
The important point is that Judge B generally is not jurisdictionally compelled to reach the same result merely because Judge A got there first.
Do Not Turn the Doctrine Into Judge-Shopping
A lawyer should not read these cases as authorization to file the identical motion repeatedly in hopes of eventually drawing a more receptive judge.
Courts possess ample authority to manage abusive or repetitive motion practice.
Repeated motions can:
-
waste judicial resources;
-
damage counsel’s credibility;
-
increase litigation costs;
-
invite sanctions in an appropriate case;
-
violate scheduling orders;
-
run afoul of procedural rules; and
-
irritate the very judge counsel hopes to persuade.
There should be a legitimate reason for asking the court to revisit an issue.
Explain Why the Court Should Reconsider
A renewed motion should not simply pretend the earlier ruling never happened.
Usually the better advocacy is to confront it.
Explain:
The prior ruling was interlocutory.
Then explain why reconsideration is appropriate.
Perhaps:
-
discovery has materially changed the record;
-
an expert opinion failed to develop as anticipated;
-
deposition testimony eliminated a factual dispute;
-
new controlling authority has been issued;
-
the first motion involved pleading sufficiency rather than proof;
-
the issue now arises under a different procedural standard;
-
trial evidence differs materially from the summary-judgment record; or
-
the prior legal analysis was demonstrably incorrect.
That is advocacy.
Simply hoping the second judge does not notice the first ruling is something else.
The Doctrine Can Be Strategically Important to the Losing Party
Suppose a defendant loses a significant pretrial motion.
The ruling is interlocutory and not immediately appealable.
The defendant should not automatically conclude that the issue is gone forever.
Counsel should determine:
-
whether the ruling remains interlocutory;
-
whether additional discovery may materially change the record;
-
whether a renewed motion is permitted;
-
whether the issue can be raised at summary judgment;
-
whether it can be preserved through a motion for judgment at trial;
-
whether an interlocutory appeal is independently authorized;
-
whether Rule 2-602(b) certification is available and appropriate; and
-
how the issue must be preserved for eventual appellate review.
Losing an interlocutory motion may be the beginning of the issue, not its end.
The Doctrine Is Equally Important to the Winning Party
The winning lawyer should also understand the limited nature of the victory.
If a motion to dismiss is denied, continue developing evidence supporting the claim.
If summary judgment is denied, prepare to establish every required element at trial.
If an evidentiary ruling is favorable before trial, determine whether the ruling is definitive and what must be done to preserve the issue if it arises differently during trial.
Do not allow an interlocutory victory to substitute for proof.
Final Judgment Changes Everything
The freedom to revisit interlocutory rulings should not be confused with authority to disregard final judgments.
Once a final judgment has been entered, different rules govern revisory power, post-judgment motions, and appeals.
Maryland Rule 2-535, for example, governs revisory power over judgments in circumstances materially different from Rule 2-602’s treatment of interlocutory orders.
Likewise, principles of appellate jurisdiction, res judicata, and finality become relevant in ways they ordinarily are not during ongoing interlocutory proceedings.
The first question should therefore always be:
Was the earlier ruling actually final?
An Appellate Mandate Is Different Again
Once an appellate court decides an issue and returns the case to the circuit court, the trial court does not possess the same freedom to reconsider the appellate court’s legal determination.
The mandate rule and law-of-the-case principles constrain proceedings on remand.
A circuit judge cannot use the nisi-prius doctrine to overrule the Appellate Court of Maryland or Supreme Court of Maryland.
That is not reconsideration of a coordinate trial judge.
It is disregard of superior appellate authority.
An Important Distinction: Discretion to Reconsider Versus Correctness of the New Decision
A second judge’s authority to reconsider an interlocutory ruling does not mean the second ruling is substantively correct.
These are separate questions.
A party may argue on appeal:
Judge B had authority to reconsider the matter, but Judge B reached the wrong legal result.
The appellate court can agree with the first proposition and still reverse on the second.
Thus, the nisi-prius rule concerns authority and finality.
It does not insulate the later decision from ordinary appellate review.
Practical Example: Medical Malpractice
Assume a defendant physician moves to dismiss a malpractice count, arguing that Maryland law recognizes no duty under the pleaded circumstances.
Judge A denies the motion.
Discovery proceeds.
The plaintiff’s expert is deposed.
The expert’s testimony establishes a materially narrower factual basis than the complaint suggested.
The defendant moves for summary judgment before Judge B.
The plaintiff argues:
Duty has already been decided.
That may be incorrect.
Judge A ruled on the complaint.
Judge B has a developed factual record.
The earlier ruling was interlocutory.
Judge B may have authority to reconsider the legal issue in light of the record now before the court.
Practical Example: Premises Liability
A property owner moves for summary judgment, arguing that the condition was open and obvious.
Judge A denies the motion because photographs and deposition testimony create a factual dispute.
At trial, however, the plaintiff’s testimony eliminates the factual premise upon which the summary-judgment opposition depended.
The defendant moves for judgment.
The plaintiff cannot necessarily defeat the motion merely by pointing to Judge A’s summary-judgment ruling.
The trial judge must evaluate the evidence actually presented.
Practical Example: Causation
Judge A denies summary judgment because the plaintiff’s expert report appears to supply legally sufficient causation testimony.
At trial, the expert retreats from that opinion on cross-examination and concedes that the causal proposition cannot be stated to the required degree of probability.
The earlier summary-judgment ruling does not guarantee submission to the jury.
The evidentiary record has changed.
The trial judge decides the case actually tried.
Practical Example: The Record Has Not Changed at All
The harder situation arises when:
-
the same issue is presented;
-
the same record exists;
-
the same legal authorities control;
-
and the only material difference is the identity of the judge.
The second judge may still possess revisory authority over an interlocutory order.
But the absence of any changed circumstance can weigh strongly against exercising that discretion.
That is where institutional comity, efficiency, consistency, and fairness assume greater importance.
The question becomes not simply:
Can I ask again?
but:
Why should the court decide differently this time?
A Useful Motion Checklist
Before asking a Maryland circuit court to revisit an earlier ruling, determine:
-
Was the earlier ruling final or interlocutory?
-
Did it resolve all claims against all parties?
-
Was judgment certified under Rule 2-602(b)?
-
Has an appellate court decided the issue?
-
Is there an appellate mandate?
-
Has the factual record changed?
-
Has controlling law changed?
-
Is the procedural standard different?
-
Is the renewed motion authorized by the applicable Maryland Rule?
-
What legitimate reason justifies reconsideration?
-
Has the issue been preserved?
-
Does the scheduling order restrict further motions?
-
Is the potential benefit worth the risk of appearing repetitive or abusive?
The same checklist works in reverse for the party defending an earlier favorable ruling.
The Larger Lesson: Interlocutory Means Interlocutory
Lawyers understandably want certainty.
Once a judge decides an issue, everyone would prefer to know that the decision will remain in place.
But Maryland civil procedure deliberately preserves substantial trial-court authority over rulings that have not become final judgments.
That flexibility serves a purpose.
Cases develop.
Evidence changes.
Legal issues become clearer.
Experts change opinions.
Claims disappear.
Appellate decisions are issued.
An interlocutory ruling that made perfect sense six months earlier may no longer make sense when the case reaches trial.
The price of that flexibility is some uncertainty.
Bottom Line
A Maryland circuit-court judge generally is not bound by another judge’s earlier interlocutory ruling in the same case.
The later judge ordinarily possesses discretion to reconsider the matter de novo.
That means:
A denied motion to dismiss does not necessarily prevent later summary judgment.
A denied summary-judgment motion can be renewed.
Surviving summary judgment does not guarantee that the claim reaches the jury.
A partial interlocutory ruling may remain subject to revision.
A different judge may reach a different conclusion.
But:
A final judgment is different.
A controlling appellate decision is different.
An appellate mandate is different.
And discretionary authority to reconsider is not permission for repetitive judge-shopping.
The practical lesson for the lawyer who wins an interlocutory motion is:
You won the motion. You did not necessarily win the issue forever.
The practical lesson for the lawyer who loses is equally important:
Before abandoning the issue, determine whether the ruling was actually final.
In Maryland’s nisi prius courts, the distinction between an interlocutory ruling and a final judgment is not merely procedural terminology.
It can determine whether an issue that appeared to have been decided months—or even years—earlier remains very much alive when the case reaches another judge.
